I’m planning to purchase a used T480, and want to know how the battery life would be on Linux. Online I see a lot of good numbers, and I am considering carrying multiple of the external batteries, but I want another opinion. Also, do you have any recommends on a good price to “go for it” and any other laptops to consider (up to but preferably well under 600 USD, good battery/portability, linux) to consider.
All thinkpads (at least all T series) have easily swappable batteries. The T480 has 2 batteries, one external and one internal. Older models had only external, newer models have only internal. The only advantage of the T480s battery setup is that you can get 100 watt hours in the laptop. The gen that came out right after it only has like 50 or 60, but I think the T14 gen 3 and newer machines have bigger batteries.
